Following the award of a Maritime Usage Licence by MARA, EirGrid commenced Phase 1 marine and coastal surveys for the Powering Up Offshore – South Coast Tonn Nua grid connection in July 2025. This campaign initiated extensive offshore geophysical investigations across potential export cable route corridor options from Maritime Area A (Tonn Nua) as part of defining transmission routes and offshore substation locations.
